appDelegate添加，影响全局

[MMPlaceHolderConfig defaultConfig].lineColor = [UIColor redColor];
    [MMPlaceHolderConfig defaultConfig].lineWidth = 1;
    [MMPlaceHolderConfig defaultConfig].arrowSize = 5;
    [MMPlaceHolderConfig defaultConfig].backColor = [UIColor clearColor];
    [MMPlaceHolderConfig defaultConfig].frameWidth = 0;
    [MMPlaceHolderConfig defaultConfig].visibleKindOfClasses = @[UIImageView. class];

     // using it for frame debug    [MMPlaceHolderConfig defaultConfig].autoDisplay = YES;
    [MMPlaceHolderConfig defaultConfig].autoDisplaySystemView = YES;
    [MMPlaceHolderConfig defaultConfig].showArrow = YES;
    [MMPlaceHolderConfig defaultConfig].showText = YES;

     // using it to control global visible    [MMPlaceHolderConfig defaultConfig].visible = YES;

使用的时候添加，影响单个

[iv2 showPlaceHolder];
    [iv3 showPlaceHolderWithLineColor:[UIColor greenColor]];
    [iv4 showPlaceHolderWithLineColor:[UIColor yellowColor] backColor:[UIColor colorWithRed: 0.1 green: 0.1 blue: 0.1 alpha: 0.5]];
    [iv5 showPlaceHolderWithLineColor:[UIColor whiteColor] backColor:[UIColor colorWithRed: 1.0 green: 0.5 blue: 0 alpha: 0.8] arrowSize: 12];
    [iv6 showPlaceHolderWithLineColor:[UIColor whiteColor] backColor:[UIColor blackColor] arrowSize: 25 lineWidth: 3]
